Serving as his second lightsaber, Windu constructed it after many years of experience and used the highest standards to make a superior weapon. In addition to a specially designed handgrip, the lightsaber's electrum finish indicated Windu's status as a senior member of the Jedi High Council.[1]

Prior to the end of the Clone Wars, Windu fought Darth Sidious in a last-ditch effort to save the Jedi Order.

Refusing to accept defeat, Sidious attacked Windu with a blast of Force lightning, forcing the Jedi Master to block the lightning with his lightsaber. As a result, the lightning was redirected to its source, leaving Sidious' face disfigured in the process.[11] Before he could strike down the Sith Lord, the Jedi Knight Anakin Skywalker used his own weapon to sever Windu's hand in order to save Sidious' life.[8] With Windu injured by his former ally[12] and bereft of his lightsaber, Sidious renewed his attack by unleashing torrent of Force lightning,[11] resulting in the death of the Jedi Order's great champion.[8]
